Blood PSA testing is used as a screening test for prostate cancer. Prostate-specific antigen (PSA) levels by age remain the same across most populations. A PSA level above 4.0 ng/mL in any age group must be investigated. However, PSA levels can spike in noncancerous conditions, such as ...
What PSA level indicates BPH? High PSA levels do not always mean that you have prostate cancer or any other prostate problem. Many factors can affect your PSA levels. Therefore, your doctor won’t consider your PSA level on its own. There is no specific normal or abnormal level of PSA...
PSA Tests The prostate gland produces a protein called prostate specific antigen (PSA). Most of the PSA is removed from the body with semen, but some of it ends up in the bloodstream. Normally, this is a very small amount that is either free floating or bound to other substances. ...
In addition, normal results can occur even when cancer is present (false negative). As seen in the table a small number of men with a low PSA level may still have prostate cancer although this is usually likely to be at a very early stage. A normal result for a man over 55 can be...
A PSA test measures nanograms of PSA per milliliter (ng/mL) of blood. But if you have no symptoms, the usual guidelines for total PSA levels are: Safe. Zero to 2.0 ng/mL. Your chance of prostate cancer is very low. Checking your free PSA level may be unneeded. Safe for most. Bel...

Prostate-specific antigen (PSA) blood test. HighPSAlevels may be a sign of a larger-than-usual prostate. A doctor can also order it as a screening test for prostate cancer. Advanced tests Based on the results of those tests, your doctor may order more tests to rule out other problems or...
activity. However, most patients who have prostate cancer will also have a higher than normal or rising PSA blood test because of cancer’s growth activity. For this reason, prostate cancer becomes “the usual suspect.” This is why doctors want to rule cancer in or out as quickly as ...
A lack of available evidence underlies the diversity of opinion regarding the management of asymptomatic prostate cancer patients with a rising PSA. The need for randomized controlled trials in this area is highlighted. 展开 关键词: Prostate cancer Asymptomatic Intervention PSA Androgen ablation ...
Your doctor may just be able to keep an eye on your PSA level. (This is called active surveillance.) As long as it stays around the same, your cancer cells likely aren't growing or spreading. This means you don't need surgery or radiation therapy that can cause side effects and ...
